Reference output: introduction to a book by another author?

Hi!

The problem I have is this: how can insert, in endnote X2, the author of a book of which I am citing the introduction. E.g. Tom Introducer has written an introduction to Conrad’s Nostromo edited by Harry Editor, how would I be able to get in the name of Conrad? In MLA style this would normally give this:

Harry, Tom. “Introduction.” Nostromo. By Joseph Conrad. Ed. Harry Editor. London: Some Publisher, year.

I’m new to this forum and could not immediately find this sort of question answered. If somebody can help me or refer me to another topic, my thanks.

Found it: there is an “original publication” entry.
